Parameter Analysis

The 330710-000-050-50-02-CN is designed for use with a 5-meter Proximitor sensor only, ensuring matched impedance and optimal performance. The probe’s DC resistance of 7.2 ± 0.8 ohms is critical for accurate signal transmission. The recommended minimum target diameter is 30.5 mm for flat surfaces and 152 mm for shafts, ensuring reliable measurements without cross-talk. The PPS tip and stainless steel case provide durability in harsh environments.

Application Scenarios

This proximity probe is ideal for monitoring vibration and position in critical rotating machinery such as turbines, compressors, pumps, and other industrial equipment. It is commonly used in power generation, oil & gas, petrochemical, and manufacturing industries where reliable condition monitoring is essential to prevent downtime and ensure safety.

Installation Guide

Install the probe with the recommended torque of 63.3 N•m (560 in•lb) for the M16x1.5 case. Ensure the probe tip is properly positioned relative to the target surface, maintaining the recommended minimum target sizes. The connector should be finger tight, with a maximum torque of 0.565 N•m (5 in•lb). Avoid bending the cable beyond the minimum bend radius of 25.4 mm (1.0 in).

Compatibility

This probe is compatible with Bently Nevada 3300 XL series Proximitor sensors, specifically the 5-meter version. It is designed for use with the 3300 XL system and is suitable for integration with Bently Nevada racks and monitors.

Maintenance Advice

Regularly inspect the probe cable and connector for damage. Ensure the probe tip is clean and free from debris. Avoid exposing the probe to temperatures below -34°C (-30°F) as this may cause premature failure of the pressure seal. Periodically verify the probe resistance to ensure it remains within specification.

Procurement Advice

When ordering the Bently Nevada 330710-000-050-50-02-CN, verify that the total length (5.0 meters) matches your Proximitor sensor requirement. Confirm the connector type and agency approval (CN) for your region. For technical support or to ensure compatibility, contact TenBN authorized channel.
